Nilight SPST Multi Purpose Relay 12V 5 Prong Fuel Pump Relay 5Pack 35A/20A Ultra Micro ISO Automotive Replacement Accessory Power Relays for Automotive Cars Truck tractor Marine Boat, 2 Years Warranty

I’ve used a bunch of these over the last several years. The price is really good, and they perform as well or better than the parts store, relays; and the fact that it has a pigtail, makes them useful for more than just replacement relays.I don’t think I’ve seen any of them fail yet. But I’ve had the cheaper lines from the big-name parts stores fail in six months or less. I’ll keep buying these as long as they keep performing long-term.

Great product

They seem decent for what they are. The relay seems well made and the pigtail harness seems to fit well. The relay itself doesn't look very water resistant and the harness certainly isn't. Should be fine where I plan to mount them.

The price is certainly right! What I like about this product is that it includes the connection socket with colored wires. What I found difficult with this product is that the connection socket slots are not perfectly aligned to accept the blades of the relay assembly. (It appears the socket was assembled without care). If one attempts to insert the relay assembly with force, it will damage the socket since not all of the blades line up to the haphazardly assembled socket. One has to first carefully match the relay blades to each slot in the socket by slightly bending the ones that don't fit precisely. Then the relay will insert without damage or difficulty.My brother's Jeep has messed up wiring in the low beam headlight circuit somewhere in the wiring loom. We used one of these relays to just rewire the low beam circuit to go around the bad wiring. The relay is controlled by the regular low beam switch on the steering column so the car still functions as if its original wiring was still in play. (We disconnected the original wiring from the low beam light filaments and replaced it with the output of the newly installed relay)! So far, it has been working perfectly for the past 2 weeks! What is still a mystery is how long will this relay continue to function seeing as it is from China?As an aside, one should 'cap off', (or at least tape off), the end of the unused red wire. It is a funtional wire connection to the relay that is not normally used.

I have a 1988 old Mazda truck where the wire is all worn out. I’ve recently made a custom wiring harness and got rid of all the older relay from the factory and replaced it with these newer ones. These new relay seem to be working very good, I didn’t have any issue as of right now.Another benefit of replacing a older relay with these newer one is that you could always find exact part to replace it without having to redo the whole wiring again.I would highly recommend this relay if you are building a custom wiring.

Priced right and good quality

Instructions were vague but with a little bit of knowledge you can install it. I used one for my train horns.

Once a person considers the needs for a relay panel, it becomes evident that these items do not best suit the situation. It is far better to anchor the sockets, rather than the relays. Anchoring of relays requires removal of a screw, whereas anchoring the socket allows the relay to be easily replaced.Making this set worse, is the fact that the sockets do not slide together easily. They start alright, but they do not continue to slide all the way without unnecessary force.Further, the idea of interconnection offers no improvement to the wiring layout of the panel.I do not recommend this product, and I am sorry I bought it.

Muy rápida entrega

they work great and are way cheaper than buying at local stores.

Excelente producto y a un precio inigualable, la calidad esta de 10, de ser necesario lo volvere a comprar, imcluye su arnes y permite ver la numeracion ademas de incluir un diagrama para facilitar la instalacion.

The harness looks decent, contacts are tight, copper wires are thick, although I can't find any ratings or gauge on the jackets. The set is also inexpensive compared to local auto parts shops.A word of caution, though: in the diagram provided (which also comes in the box, to my surprise - nice touch), there's a rocker switch we know nothing about, except that it has three terminals. If you take a typical SPDT rocker switch and connect it according to the diagram, you'll short-circuit the battery (see picture), which is a *fire hazard* (even if the fuse is there). So I'm guessing they meant to depict an illuminated SPST switch, which would look very similar, and would have the same three terminals, but one has a different color (that one is for the internal light circuit). And if that's the case, the wiring in the diagram still doesn't look right based on the switches I have here - so please make sure you know what you're doing before you power up the whole circuit.Edit: I forgot to write about the relays. I was a little worried after reading reviews saying the wrong items were sent. Well, I got the right ones (5-pin), and they all work. As for quality and durability, I can't say much at this point. Need more time to try them.

Son exenlentes para conectar faros y ventiladores en el auto y son muy buena calidad vienen sellados para protegerse de la humedad
